A single-case report details robotic partial central hepatectomy and bile-duct resection with Roux-en-Y reconstruction for gallbladder adenocarcinoma—an example of a complex operation performed minimally invasively, not evidence that it is ready for routine use.

• The Hepp-Couinaud maneuver was used for the biliary anastomosis.
• Operative time was 240 minutes, blood loss 150 mL; the patient had no complications and was discharged on day 8.
• No recurrence was reported at 12 months.

Useful as a technical description for experienced hepatobiliary teams; one case cannot establish safety, reproducibility, or oncologic equivalence to open surgery.
